ET7136 13.56Mhz HF RFID School Bus GPRS Reader

1. General

Radio Frequency Identification RFID is the acronym for radio frequency identification, commonly known as RFID. Radio Frequency Identification RFID is a non-touch automatic identification technology, radio frequency signal through the automatic target recognition and access to relevant data, to identify without human intervention, it can work in a variety of harsh environments. RFID technology can identify the high-speed moving objects, also identify multiple tags, the operation is quickly and conveniently.

Shenzhen eTel technologies co., ltd. according to market demand of the wireless internet of things RFID, Combine with GPRS FAM function, develop ET7136 RFID GPRS Reader, it able to real time send RFID TAG information via the GPRS network to data center. Data center platform will receive the data and save into database, users can just use browser to access data and view all information.

ET7136 RFID Reader is mainly used in schools, residential security, plant access, government access control, automotive systems, ET7136 RFID Reader also support FAM feature, which supports 3 DI, 1 DO, 1 AI, 2 TE ports, it can be connected to different sensors to cooperate with RFID function.

ET7135 can be choose GPS function, according to market demand of the GPS location management, Combine with GPRS RFID function, ET7136 school bus reader is able to real time send GPS location and RFID TAG information via the GPRS network to data center. Data center platform will receive the data and save into database, users can just use browser to access data and view all information.

2. Feature

·           Industrial Design

ET7136 RFID Reader is industrial design which built-in watchdog chipset to ensure the system work continuously, Watchdog monitoring the GPRS module and CPU all the time, if the GPRS module or CPU does not response for long time, Reader will restart automatically. Reader is very suitable for long-term continuous work applications.

·           GPS locating (Optional)

Real-time checking the location of the vehicles, terminal device will automatically report position, monitoring Center will automatically pop-up map showing the current location of vehicles.

·           Main and backup data center

ET7136 RFID Reader support main and backup data center, user can set both main data center IP address or domain name, when Reader  fail to connect with main data center, it will try to connect backup data center automatically.

·           TAG buffer

ET7136 RFID Reader can save the TAG card information in the NVRAM buffer, if the GPRS network is abnormal, the reader will save data in the NVRAM, when the network returns to normal, the data will be sent immediately. NVRAM has feature for save data even power lose, so even reader power lose, Tag data will still save in the NVRAM.

·           TAG Packet Series Number

All TAG data packet include serial number, Data center need to reply a corresponding serial number of the ACK packet after received TAG packet, readers receive the ACK packet, then delete the TAG information from the buffer, otherwise it will resend TAG packet (as specified time interval and frequency). This feature is based on the GPRS network feature, to ensure TAG data doesn't lose.

·           Embedded Li-battery and Temperature sensor

ET7136 RFID Reader built-in 1000mA Lithium battery, it can work for 3 hours if the external power supply cut off. the built-in temperature sensor can real-time monitoring of environment temperature, and the outside TE port can be extended to the user device surface to monitoring equipment temperature.

·           SMS Remote Restart

ET7136RFID reader supports SMS remote control, users can query the device working status through SMS, also user can reboot reader through SMS.

·           DO port programmable output

ET7136 RFID Reader DO (digital output) port supports programmable output, according to the requirement of user site, the level of output level, switching time, times would be programmable.

·           Zone type

FAM DI ports support zone type setting which can be set to as common zone, delay zone, intelligent zone, emergency zone, home zone, according to the user site conditions and sensor type, set the correct zone type to prevent false alarm, missing alarm.

·           SMS Backup

FAM communication with the RFID data center through GPRS; if GPRS disconnect, FAM can send the TAG information via SMS for backup tunnel.

·           Timing arm/disarm, password arm/disarm

FAM support timing arm/disarm function, it can perform a specified time every day to arm/disarm; FAM also support any mobile phone number via a password to arm/disarm, after the instruction is executed successfully, FAM will arm/disarm information to the administrator phone as well.

·           Camera capture picture

FAM provides the interface to connect with camera, real-time remote image capture, with the FAM IO ports, real-time capture images when an alarm is generated, and sent to the data center; FAM can be set to a fixed time interval for continuous capture images as well.

·           Clock synchronization

ET7136 Reader support clock synchronization; it can read the clock from SMS or get clock from management platform by GPRS.

·           Graphical configuration software

ET7136 RFID Reader provides full graphical software configuration, easy to use, and supports import or export configuration file; so users just simply click a few icons to quickly setup RFID system.
